Specification of Letters Patent.

Application filed March 26, 1918. Serial No. 224,882.

I To all whom it may concern:

Be it known that I, WALTER II. CLARKE, a citizen of the United States, residing at Akron, in the county of Summit .and State of Ohio, have invented .certain new and useful Improvements in Rubber Heels, of which the following is a specification.

This invention relates to cushion heels, and more especially to those which are detachable; and the object of the same is to provide a rubber heel made in two'layers or lifts, one of which is permanently attached beneath the sole, and the other of which is detachably connected with the first and replaceable when it becomes worn.

This object is carried out b constructing the parts in a manner hereina ter more fully described and claimed, and as shown in the drawings, wherein Figure 1 is a side elevation of a shoe therefore whoseheel is constructed in accordance with this inventlon,

Fig. 2 is a transverse and Fig. 3 a longitudinal section through the heel proper and a portion of the sole and pp Fig. 4 is a perspective view of the cap element of this improved heel in its normal position, and

Fig. 5 a similar view of it inverted,

Fig. 6 is a perspective view of the tread element of this invention.

The upper U is brought down to and fastened upon the sole S in any appropriate manner, and beneath this sole is to be fastened my improved heel. I have shown the entire heel made up of two rubber members, but it is obvious that the heel could have some leather lifts next the sole and the rubber heel could be only the two lower lifts of such a heel. However, we are concerned only with the rubber parts or members.

The upper or cap member 1 may be secured beneath the sole S in any suitable manner. In Fig. 3 I have shown a long nail driven upward at N, and a staple driven downward at D, but it is quite possible to cement this cap member beneath the sole or to sew it there; and as above suggestedflt,

may not be the sole to which it is attached, as there may be one or two leather lifts between this member and the sole. .If nailed thereto, the, member will have appropriate through its lower face, and which-where they do open through said lower face have contracted mouths 4. Also I provide the lower face of this member with a dove tailed tongue 5 and as shown it is dove-tailed in cross section whereas it is triangular in plan, tapering from the front edge 6 of this member back to a point 7 standing about midway between the two sockets 3. I would have this tongue depend wholly below the thickigess of the lift constituting the upper mem- The lower member or tread 11 conforms in size and contour with the upper member, and although it is of rubber it may be of a different grade of rubber without departing from the principle of my invention. Within its body is formed a recess or groove 15 having undercut side walls converging from its mouth 16 to a sharp angle 17 near the rear portion of the heel, and this entire groove is of a size and shape to receive the dovetailed tongue 5. At appropriate points there rise from the upper face of this tread member two headed studs 13, their shanks 14 being reduced as shown. lhese studs are approximately the same shape as but a little larger in size than the sockets 3 which they are intended to fit; and, while made integral with the said member, they may or may not be reinforced as desired. This member .may not be as a whole as thick as the cap member, but I do not wish to be limited in above.- Then the tread member is brought into position and its groove engaged with the tongue of the cap member already in place, its sides being bent down until the studs 13 may slide along the lower face of the cap until the tongue and groove are in thorough engagement. Now a sharp blow or two with a hammer or similar tool will cause the heads of the studs to pass through the contracted mouths 4 of the sockets until the heads stand in the enlarged upper portions thereof and the shanks 14 in the mouths 4, and by this means the members are locked together without having to use any nails or fastening devices in the tread member. The shoe is now used as usual and when the tread member becomes worn, it may be removed and replaced without necessarily taking 05 the cap member at all. If the outer member of the heel should run down on the outside, for instance, after these members become worn they can be taken off and transferred, as will be clearly understood. I do not wish to be confined to the exact details of parts and where I have spoken of rubber I 0 course include any similar material or composition consisting of several materials. Jspecially do I desire to call attention to the fact that, while I have described and claimed my invention as a heel which is secured to and underlies the rear end of the sole S, it is quite possible that it could be continued throughout the full length of the sole so as to supply a rubber facing thereto, or it might even be used as a facing for the forward part of the sole, and some other kind of a heel employed. In other words, this invention is not strictly a rubber heel, although so illustrated in the drawings.

What is claimed as new is 1. In a two-part rubber heel,'the combination with a cap member having through its body a plurality of sockets which are larger at their upper ends than at their lower ends;

of a lower member having upstanding integral headed studs shaped and disposed to fit said sockets when driven thereinto, and addi- Eional interlocking means between said memers.

2. A two part rubber heel comprising a cap member having a pair of sockets through its body and a triangular dove-tailed tongue on its lower face extending between said sockets, and a tread member having a pair of headed studs rising integrally from its upper face to engage said sockets and a groove in said face extending between said studs and adapted to receive said tongue.

Intestimony whereof I aifix my signature in presence of two witnesses. 1
